PUMP-PIPE INSERTOR AND REMOVER.

Specification of Letters Patent.

Patented Nov. 22, 1910.-

Application filed March 9, 1910. Serial No. 548,234.

T o all whom it may concern:

Be it known that I, VVADDILL L. RHODES, a citizen of the United States,residing at Lonie, in the county of Childress and State of Texas, haveinvented certain new and use ful Improvements in Pump-Pipe Insertors andRemovers, of which the following is a specification.

My present invention relates to that class of pipe lifting apparatuswhich embodies lifting and holding frames of similar construction, thelatter of which is detached, and the former of which is connected to alever for raising and lowering the same, and my object is to providecertain novel elements of construction and arrangement which will permitof greater leverage and power of the lifting frame and also permit ofits reversal whereby upon the reversal of the holding frame of theapparatus may be used to insert a pump pipe in the ground.

With this in view my invention resides in the features of constructionand arrangement to be hereinafter specifically pointed out withreference to the accompanying drawing, wherein,

Figure 1 is a front elevation of my improved apparatus, the lifting andholding frames being broken away to show the intermediate parts. Fig. 2is a side elevation thereof. Fig. 3 is a view similar to Fig. 1, withthe frames reversed, and Fig. 4c is a plan view of the lifting frameremoved.

Referring now to these figures, the lifting and holding frames 10 and 11are of similar construction, each embodying parallell bars 12 throughthe ends of which extend transverse bolts 13, these bolts extending alsothrough members 14 interposed between the bars for the purpose ofspacing themapart suitably to receive the pipe therebetween. Interposedbetween the bars 12 intermediate blocks or members 14, are dogs 15 and16, upon bolts 17 through said bars, dog 15 being stationarily clampedwhile dog 16 1s movable upon its bolt as a pivot and held from movementin one direction by the engagement of its cam-shaped outer end 18against the adjacent spacing member 14. The inner opposing ends of thesedogs 15 and 16, are serrated as shown, and this end of the movable dog16 is also rounded. One of the bars 12 of each of the frames may alsohave a leaf spring 19 to bear against the movable dog 16 to tension themovement thereof in one direction.

In operation, the holding frame 11 rests upon the ground to hold a pipewhen the lifting frame 10 is lowered to take a fresh grip thereon, thelatter frame having its spacing member provided with outstandinoqrounded projections 20, extending beyond the ends of the bars 12thereof, and forming trunnions therefor, to engage within slots 21 inthe side arms of a yoke 22 at one end, and forming a part of, theoperating lever 23 which is intermediately fulcrumed at the upper end ofa tripod or supporting frame 24 which thus supports the lifting frame ashort distance above the holding frame. This connection of the liftingframe permits it to slide with relation to the lever as the pipe islifted and prevents binding. It also permits of longer leverage and morepowerful action, and is such that the lifting frame may be readilyreversed, whereby when the holding frame is reversed accordingly, a pipemay be forced down into a well, as shown in Fig. 3.

I claim:

The combination of lifting and holding frames, each comprising parallelside bars having connecting means adjacent their ends, and spacingmembers therebetween through which said connecting means pass, and eachhaving intermediate opposing dogs, the spacing members of the liftingframe having rounded extensions projecting longitudinally beyond theends of the frame, a supporting frame, and a lever fulcrumed upon saidframe and having a yoke at one end provided with slots in its sidepieces to slidably and rotatably receive the said extensions of saidlifting frame, for the purpose described.

In testimony whereof I aiiix my signature in presence of two witnesses.

WADDILL L. RHODES.
